TECHNICAL FIELD
[0001] The present invention is directed generally to an adaptable lighting unit and an
adaptable lighting system. More particularly, various inventive apparatus and systems
are disclosed herein that relate to an LED-based lighting unit that may adaptably
achieve a plurality of lighting effects.
BACKGROUND
[0002] Digital lighting technologies, i.e. illumination based on semiconductor light sources,
such as light-emitting diodes (LEDs), offer a viable alternative to traditional fluorescent,
HID, and incandescent lamps. Functional advantages and benefits of LEDs include high
energy conversion and optical efficiency, durability, lower operating costs, and many
others. Recent advances in LED technology have provided efficient and robust full-spectrum
lighting sources that enable a variety of lighting effects in many applications. Some
of the fixtures embodying these sources feature a lighting module, including one or
more LEDs capable of producing different colors, e.g. red, green, and blue, as well
as a processor for independently controlling the output of the LEDs in order to generate
a variety of colors and color-changing lighting effects, for example, as discussed
in detail in
U.S. Patent Nos. 6,016,038 and
6,211,626, incorporated herein by reference.
[0003] Manufacturers currently offer a large number of different lighting units for implementation
in lighting fixtures. Each lighting unit often has a different form factor and/or
creates a different type of lighting effect. For example, thousands of different LED-based
lighting units may be offered, with each including a unique form factor and/or the
capability of producing a unique lighting effect. Each of the LED-based lighting units
may optionally be optimized for a specific lighting fixture and/or specific intended
application. However, some customers may have difficulty in choosing an appropriate
lighting unit from the variety of different lighting units that are offered.
[0004] Thus, there is a need in the art to provide a lighting unit that may adaptably achieve
a plurality of lighting effects and that may optionally overcome one or more drawbacks
of conventional approaches.
[0005] GB 2 453 540 discloses a light unit for use with other light units to form a multi-light unit
array including a control circuit for controlling the energization of at least one
light source, such as an LED, provided on the light unit and having a receiver for
wirelessly receiving a control signal from an external transmitter.
[0006] DE 10 2010 013561 discloses a device that has a light connected to a controller for supplying energy
to the light, and a data channel provided between the controller and a control unit.
The controller and the control unit exchange characteristic data e.g. current parameter
data, temperature control data, base current data, of the light over the data channel.
The controller includes an indicator with an indicator value, and the characteristic
data of the controller is conveyed to the control unit, during initialization of the
control unit depends on the indicator value.
SUMMARY
[0007] The present disclosure is directed to inventive methods and apparatus for a lighting
unit that may adaptably achieve a plurality of lighting effects. For example, a plurality
of LEDs producing a light output having at least one adaptable light output characteristic
may be provided and controlled by a controller electrically coupled to the plurality
of LEDs. The controller may control the at least one adaptable light output characteristic
in accordance with received lighting configuration data that is specific to a particular
lighting implementation.
[0008] Generally, in one aspect, the invention relates to an adaptable LED-based lighting
unit that includes a plurality of LEDs producing a light output having at least one
adaptable light output characteristic, and a controller electrically coupled to the
plurality of LEDs and controlling the at least one adaptable light output characteristic
in accordance with received lighting configuration data. The lighting configuration
data is selected from a set of predefined lighting configuration data, is received
in response to integration of the LEDs within a particular lighting implementation,
and is specific to the particular lighting implementation.
[0009] In some embodiments, the lighting unit includes at least one storage medium in communication
with the controller, which stores the lighting configuration data and transmits the
lighting configuration data in response to integration of the LEDs within the particular
lighting implementation. In some versions of those embodiments, the controller requests
the lighting configuration data from the storage medium in response to receiving lighting
implementation data indicative of the particular lighting implementation. The lighting
implementation data and the lighting configuration data may optionally be correlated
to one another in a look up table of the storage medium. The lighting implementation
data may optionally include at least one of the following: specific lighting fixture,
lighting fixture type, lighting fixture shape, and specific lighting effect. The lighting
unit may optionally further include an RFID reader which receives the lighting implementation
data and transmits the lighting implementation data to the controller.
[0010] In some embodiments, the lighting unit further includes an RFID reader which receives
the lighting configuration data and transmits the lighting configuration data to the
controller.
[0011] In some embodiments, of the lighting unit at least one of the adaptable light output
characteristics is a dynamic light output characteristic.
[0012] In some embodiments of the lighting unit at least one of the adaptable light output
characteristics is dimming that is controlled in accordance with the lighting configuration
data.
[0013] Generally, in another aspect, the invention relates to an adaptable LED-based lighting
system that includes a lighting configuration transmitter at least selectively transmitting
predefined lighting configuration data, an LED-based lighting unit having a plurality
of LEDs, and a controller electrically coupled to the plurality of LEDs. The controller
adjusts at least one light output characteristic of the LEDs to achieve a predefined
lighting configuration of a plurality of predefined lighting configurations, the predefined
lighting configuration being correlated with received lighting configuration data.
The lighting configuration data is received in response to integration of the LEDs
within a particular lighting implementation.
[0014] In some embodiments of the lighting system, the controller requests the lighting
configuration data in response to receiving lighting implementation data indicative
of the particular lighting implementation. In some versions of those embodiments,
the lighting implementation data and the lighting configuration data are correlated
to one another in a look up table. The lighting implementation data may optionally
include at least one of the following: specific lighting fixture, lighting fixture
type, lighting fixture shape, and specific lighting effect. The lighting configuration
transmitter may optionally be a storage medium or an RFID tag.
[0015] In some embodiments of the lighting system, the predefined lighting configuration

[0017] Generally, in another aspect, a method of adapting an LED-based lighting unit to
a particular lighting implementation is provided that includes the steps of: monitoring
for lighting implementation data indicative of a particular lighting implementation,
requesting predefined lighting configuration data corresponding to the lighting implementation

one light output characteristic of LEDs of an LED-based lighting unit to achieve a
predefined lighting configuration correlated with received lighting configuration
data.
[0018] In some embodiments, the lighting implementation data includes at least one of the
following: specific lighting fixture, lighting fixture type, lighting fixture shape,
and specific lighting effect.
[0019] As used herein for purposes of the present disclosure, the term "LED" should be understood
to include any electroluminescent diode or other type of carrier injection/junction-based
system that is capable of generating radiation in response to an electric signal.
Thus, the term LED includes, but is not limited to, various semiconductor-based structures
that emit light in response to current, light emitting polymers, organic light emitting
diodes (OLEDs), electroluminescent strips, and the like. In particular, the term LED
refers to light emitting diodes of all types (including semi-conductor and organic
light emitting diodes) that may be configured to generate radiation in one or more
of the infrared spectrum, ultraviolet spectrum, and various portions of the visible
spectrum (generally including radiation wavelengths from approximately 400 nanometers
to approximately 700 nanometers). Some examples of LEDs include, but are not limited
to, various types of infrared LEDs, ultraviolet LEDs, red LEDs, blue LEDs, green LEDs,
yellow LEDs, amber LEDs, orange LEDs, and white LEDs (discussed further below). It
also should be appreciated that LEDs may be configured and/or controlled to generate
radiation having various bandwidths (e.g., full widths at half maximum, or FWHM) for
a given spectrum (e.g., narrow bandwidth, broad bandwidth), and a variety of dominant
wavelengths within a given general color categorization.
[0020] For example, one implementation of an LED configured to generate essentially white
light (e.g., a white LED) may include a number of dies which respectively emit different
spectra of electroluminescence that, in combination, mix to form essentially white
light. In another implementation, a white light LED may be associated with a phosphor
material that converts electroluminescence having a first spectrum to a different
second spectrum. In one example of this implementation, electroluminescence having
a relatively short wavelength and narrow bandwidth spectrum "pumps" the phosphor material,
which in turn radiates longer wavelength radiation having a somewhat broader spectrum.
[0021] It should also be understood that the term LED does not limit the physical and/or
electrical package type of an LED. For example, as discussed above, an LED may refer
to a single light emitting device having multiple dies that are configured to respectively
emit different spectra of radiation (e.g., that may or may not be individually controllable).
Also, an LED may be associated with a phosphor that is considered as an integral part
of the LED (e.g., some types of white LEDs). In general, the term LED may refer to
packaged LEDs, non-packaged LEDs, surface mount LEDs, chip-on-board LEDs, T-package
mount LEDs, radial package LEDs, power package LEDs, LEDs including some type of encasement
and/or optical element (e.g., a diffusing lens), etc.
[0022] The term "light source" should be understood to refer to any one or more of a variety
of radiation sources, including, but not limited to, LED-based sources (including
one or more LEDs as defined above), incandescent sources (e.g., filament lamps, halogen
lamps), fluorescent sources, phosphorescent sources, high-intensity discharge sources
(e.g., sodium vapor, mercury vapor, and metal halide lamps), lasers, and other types
of electroluminescent sources.
[0023] A given light source may be configured to generate electromagnetic radiation within
the visible spectrum, outside the visible spectrum, or a combination of both. Hence,
the terms "light" and "radiation" are used interchangeably herein. Additionally, a
light source may include as an integral component one or more filters (e.g., color
filters), lenses, or other optical components. Also, it should be understood that
light sources may be configured for a variety of applications, including, but not
limited to, indication, display, and/or illumination. An "illumination source" is
a light source that is particularly configured to generate radiation having a sufficient
intensity to effectively illuminate an interior or exterior space. In this context,
"sufficient intensity" refers to sufficient radiant power in the visible spectrum
generated in the space or environment (the unit "lumens" often is employed to represent
the total light output from a light source in all directions, in terms of radiant
power or "luminous flux") to provide ambient illumination (i.e., light that may be
perceived indirectly and that may be, for example, reflected off of one or more of
a variety of intervening surfaces before being perceived in whole or in part).
[0024] The term "spectrum" should be understood to refer to any one or more frequencies
(or wavelengths) of radiation produced by one or more light sources. Accordingly,
the term "spectrum" refers to frequencies (or wavelengths) not only in the visible
range, but also frequencies (or wavelengths) in the infrared, ultraviolet, and other
areas of the overall electromagnetic spectrum. Also, a given spectrum may have a relatively
narrow bandwidth (e.g., a FWHM having essentially few frequency or wavelength components)
or a relatively wide bandwidth (several frequency or wavelength components having
various relative strengths). It should also be appreciated that a given spectrum may
be the result of a mixing of two or more other spectra (e.g., mixing radiation respectively
emitted from multiple light sources).
[0025] For purposes of this disclosure, the term "color" is used interchangeably with the
term "spectrum." However, the term "color" generally is used to refer primarily to
a property of radiation that is perceivable by an observer (although this usage is
not intended to limit the scope of this term). Accordingly, the terms "different colors"
implicitly refer to multiple spectra having different wavelength components and/or
bandwidths. It also should be appreciated that the term "color" may be used in connection
with both white and non-white light.
[0026] The term "color temperature" generally is used herein in connection with white light,
although this usage is not intended to limit the scope of this term. Color temperature
essentially refers to a particular color content or shade (e.g., reddish, bluish)
of white light. The color temperature of a given radiation sample conventionally is
characterized according to the temperature in degrees Kelvin (K) of a black body radiator
that radiates essentially the same spectrum as the radiation sample in question. Black
body radiator color temperatures generally fall within a range of from approximately
700 degrees K (typically considered the first visible to the human eye) to over 10,000
degrees K; white light generally is perceived at color temperatures above 1500-2000
degrees K.
[0027] The terms "lighting fixture" and "luminaire" are used interchangeably herein to refer
to an implementation or arrangement of one or more lighting units in a particular
form factor, assembly, or package. The term "lighting unit" is used herein to refer
to an apparatus including one or more light sources of same or different types. A
given lighting unit may have any one of a variety of mounting arrangements for the
light source(s), enclosure/housing arrangements and shapes, and/or electrical and
mechanical connection configurations. Additionally, a given lighting unit optionally
may be associated with (e.g., include, be coupled to and/or packaged together with)
various other components (e.g., control circuitry) relating to the operation of the
light source(s). An "LED-based lighting unit" refers to a lighting unit that includes
one or more LED-based light sources as discussed above, alone or in combination with
other non LED-based light sources. A "multi-channel" lighting unit refers to an LED-based
or non LED-based lighting unit that includes at least two light sources configured
to respectively generate different spectrums of radiation, wherein each different
source spectrum may be referred to as a "channel" of the multi-channel lighting unit.
[0028] The term "controller" is used herein generally to describe various apparatus relating
to the operation of one or more light sources. A controller can be implemented in
numerous ways (e.g., such as with dedicated hardware) to perform various functions
discussed herein. A "processor" is one example of a controller which employs one or
more microprocessors that may be programmed using software (e.g., microcode) to perform
various functions discussed herein. A controller may be implemented with or without
employing a processor, and also may be implemented as a combination of dedicated hardware
to perform some functions and a processor (e.g., one or more programmed microprocessors
and associated circuitry) to perform other functions. Examples of controller components
that may be employed in various embodiments of the present disclosure include, but
are not limited to, conventional microprocessors, application specific integrated
circuits (ASICs), and field-programmable gate arrays (FPGAs).
[0029] In various implementations, a processor or controller may be associated with one
or more storage media (generically referred to herein as "memory," e.g., volatile
and non-volatile computer memory such as RAM, PROM, EPROM, and EEPROM, floppy disks,
compact disks, optical disks, magnetic tape, etc.). In some implementations, the storage
media may be encoded with one or more programs that, when executed on one or more
processors and/or controllers, perform at least some of the functions discussed herein.
Various storage media may be fixed within a processor or controller or may be transportable,
such that the one or more programs stored thereon can be loaded into a processor or
controller so as to implement various aspects of the present invention discussed herein.
The terms "program" or "computer program" are used herein in a generic sense to refer
to any type of computer code (e.g., software or microcode) that can be employed to
program one or more processors or controllers.
[0030] The term "network" as used herein refers to any interconnection of two or more devices
(including controllers or processors) that facilitates the transport of information
(e.g. for device control, data storage, data exchange, etc.) between any two or more
devices and/or among multiple devices coupled to the network. As should be readily
appreciated, various implementations of networks suitable for interconnecting multiple
devices may include any of a variety of network topologies and employ any of a variety
of communication protocols. Additionally, in various networks according to the present
disclosure, any one connection between two devices may represent a dedicated connection
between the two systems, or alternatively a non-dedicated connection. In addition
to carrying information intended for the two devices, such a non-dedicated connection
may carry information not necessarily intended for either of the two devices (e.g.,
an open network connection). Furthermore, it should be readily appreciated that various
networks of devices as discussed herein may employ one or more wireless, wire/cable,
and/or fiber optic links to facilitate information transport throughout the network.
[0031] The term "user interface" as used herein refers to an interface between a human user
or operator and one or more devices that enables communication between the user and
the device(s). Examples of user interfaces that may be employed in various implementations
of the present disclosure include, but are not limited to, switches, potentiometers,
buttons, dials, sliders, a mouse, keyboard, keypad, various types of game controllers
(e.g., joysticks), track balls, display screens, various types of graphical user interfaces
(GUIs), touch screens, microphones and other types of sensors that may receive some
form of human-generated stimulus and generate a signal in response thereto.
[0032] It should be appreciated that all combinations of the foregoing concepts and additional
concepts discussed in greater detail below (provided such concepts are not mutually
inconsistent) are contemplated as being part of the inventive subject matter disclosed
herein. In particular, all combinations of claimed subject matter appearing at the
end of this disclosure are contemplated as being part of the inventive subject matter
disclosed herein. It should also be appreciated that terminology explicitly employed
herein that also may appear in any disclosure incorporated by reference should be
accorded a meaning most consistent with the particular concepts disclosed herein.

DETAILED DESCRIPTION
[0034] Manufacturers currently offer a large number of different lighting units for implementation
in lighting fixtures. Each lighting unit often has a different form factor and/or
creates a different type of lighting effect. Each of the lighting units may optionally
be optimized for a specific lighting fixture and/or specific intended application.
Some customers may have difficulty in choosing an appropriate lighting unit from the
variety of different lighting units that are offered. Thus, Applicants have recognized
and appreciated that it would be beneficial to provide a lighting unit that may adaptably
achieve a plurality of lighting effects and that may optionally overcome one or more
drawbacks of previous lighting units.
[0035] More generally, Applicants have recognized and appreciated that it would be beneficial
to provide various inventive methods and apparatus that relate to an LED-based lighting
unit that may adaptably achieve a plurality of lighting effects.
[0036] In view of the foregoing, various embodiments and implementations of the present
invention are directed to an adaptable LED-based lighting unit.
[0037] FIG. 1A illustrates various adaptable lighting unit modules that may interface with
one another and/or other adaptable lighting unit modules to create a desired adaptable
modular lighting unit. The adaptable lighting unit modules include a first end diffuse
lighting unit module 112 having a recess 114 therein and a second end diffuse lighting
unit module 116 having a recess 118 therein. The adaptable lighting unit modules also
include a linearly extending intermediary diffuse lighting unit module 120 and a spotlighting
unit module 122. Each of the diffuse lighting unit modules 112, 116, 120 include one
or more light sources and produce a diffuse light output. For example, one or more
of the diffuse lighting unit modules 112, 116, 120 may include a plurality of LEDs
that are paired with diffusing optics (
e.g., refracting and/or reflecting optics that are each provided over one or more LEDs)
and/or that are covered by a diffuse lens or other diffuse material provided over
the LEDs. The spotlighting unit module 122 includes one or more light sources that
produce a spot type light type output. For example, the spotlighting unit module 122
may include one or more LEDs that are paired with one or more collimating optics to
direct a spot type light output in a general desired direction. One or more of the
lighting unit modules 112, 116, 120, and 122 have one or more adjustable light output
characteristics. For example, in some embodiments each of the lighting unit modules
112, 116, 120, and 122 has a plurality of adjustable light output characteristics
such as one or more of those described herein.
[0038] The recesses 114, 118 are generally in the shape of a frustum of a pyramid and may
interface with another adaptable lighting unit module, such as spotlight adaptable
lighting unit module 122, and/or may optionally interface with another lighting fixture
component such as communications, power, and control module 130. Communications, power,
and control module 130 may include one or more drivers for powering the light sources
of the adaptable lighting unit modules 112, 116, 120 and/or 122. For example the communications,
power, and control module 130 may include an LED driver for powering LEDs of the adaptable
lighting unit modules 112, 116, 120 and/or 122. The communications, power, and control
module 130 may also include a power source and/or a connection for an external power
source to enable powering of the adaptable lighting unit modules 112, 116, 120 and/or
122. For example, power line 131 may be coupled to an external power source and may
be electrically coupled to power lines 113, 117, and/or 121 of the adaptable lighting
unit modules 112, 116, and/or 120 to provide power to the adaptable lighting unit
modules 112, 116, 120 and/or 122.
[0039] The communications, power, and control module 130 may also include a controller for
adjusting one or more light output characteristics of the adaptable lighting unit
modules 112, 116, and/or 120. For example, the communications, power, and control
module 130 may include a controller in combination with an LED driver thereof that
may manipulate the LED driver output parameters to thereby alter light output characteristics
of the adaptable lighting unit modules 112, 116, and/or 120.
[0040] The communications, power, and control module 130 may also include a transmitter
and/or a receiver for communications with one or more of the adaptable lighting unit
modules 112, 116, 120 and/or 122 and/or for communication with other components (
e.g., another device providing lighting implementation data and/or lighting configuration
data). For example, the communications, power, and control module 130 may include
a receiver for receiving lighting implementation data and/or lighting configuration
data and may adjust one or more parameters of a driver in accordance with such data.
Also, for example, the communications, power, and control module 130 may include a
receiver for receiving data from one or more lighting unit modules 112, 116, 120 and/or
122 to enable determination of one or more parameters of such modules and may optionally
adjust one or more parameters of a driver in accordance with such data.
[0041] Any transmitter and/or receiver may optionally utilize one or more communications
mediums, communications technologies, protocols, and/or inter-process communication
techniques. For example, the communication mediums may include any physical medium,
including, for example, twisted pair coaxial cables, fiber optics, and/or a wireless
link using, for example, infrared, microwave, or encoded visible light transmissions
and any suitable transmitters, receivers or transceivers to effectuate communication
in the lighting fixture network. Also, for example, the communications technologies
may include any suitable protocol for data transmission, including, for example, TCP/IP,
variations of Ethernet, Universal Serial Bus, Bluetooth, FireWire, Zigbee, DMX, Dali,
802.11b, 802.11a, 802.11g, token ring, a token bus, serial bus, power line networking
over mains or low voltage power lines, and/or any other suitable wireless or wired
protocol
[0042] FIG. 1B illustrates the adaptable lighting unit modules of FIG. 1A integrated to
form a first modular adaptable lighting unit 100A. The first modular adaptable lighting
unit 100A is substantially circular in cross-section (a cross-section perpendicular
to the page). The communications, power, and control module 130 has been received
within the recess 114 of the first end diffuse lighting unit module 112 and the spotlighting
unit module 122 has been received with the second end diffuse lighting unit module
116. The diffuse lighting unit modules 112, 116, and 120 have also been coupled to
one another. Sockets and/or other connectors may optionally be utilized. The power
lines 131, 113, 121, and 117 have also been electrically coupled to one another and
are electrically coupled to the spotlighting unit module 122.
[0043] In some embodiments, one or more of the lighting unit modules 112, 116, 120, and
122 may have one or more adjustable light output characteristics such as one or more
of those described herein. Such light output characteristics may be adjusted based
on the particular lighting implementation. For example, the light output characteristics
may be adjusted by the communications, power, and control module 130 based on determination
of which other lighting unit modules are being utilized in the first modular adaptable
lighting unit 100A. For instance, the light output intensity of each of the lighting
unit modules 112, 116, 120, and 122 may be set and/or dynamically adjustable based
on analysis of the light output capabilities of each of the lighting unit modules
112, 116, 120, and 122. Also, for instance, the power provided to each of the lighting
unit modules 112, 116, 120, and 122 may be set and/or dynamically adjustable based
on analysis of the power consumption of all of the lighting unit modules 112, 116,
120, and 122 to maintain power consumption below a desired level (
e.g., due to heat and/or energy constraints). Also, for instance, lighting implementation
data may be received indicating that the adaptable lighting unit 100A is installed
in a particular implementation and one or more of light output intensity, beam width,
color temperature, and/or distribution characteristics of each of the lighting unit
modules 112, 116, 120, and 122 may be set and/or dynamically adjustable to achieve
light output in accordance with such particular implementation.
[0044] FIG. 1C illustrates certain of the adaptable lighting units of FIG. 1A and an additional
diffuse adaptable lighting unit module 124 that are integrated to form a second modular
adaptable lighting unit 100B. The second modular adaptable lighting unit 100B is substantially
circular in cross-section. In FIG. 1C a diffuse lighting unit module 124 is received
with the recess 114 of the first end diffuse lighting unit module 112 and powering,
communications, and/or control is received from a side connection 101. In some embodiments
one or more of the lighting unit modules 112, 116, 120, 122, and 124 may have one
or more adjustable light output characteristics such as one or more of those described
herein.
[0045] FIG. 2A illustrates a puck-shaped adaptable lighting unit 200 generating a first
light output (generally represented by arrows emanating from the lighting unit 200)
that is generally directed in all directions. FIG. 2B illustrates the puck-shaped
adaptable lighting unit 200 generating a second light output (generally represented
by arrows emanating from the lighting unit 200) that is generally directed in an upward
direction. The puck-shaped adaptable lighting unit 200 includes an outer shell having
an upper surface 212, a lower surface 214, and a perimeter surface 216. The outer
shell is translucent and encloses a plurality of LEDs. In some embodiments the LEDs
may include LEDs generating a collimated beam with a fine grained control. An external
power connection 201 may provide power to the LEDs of the puck-shaped adaptable lighting
unit 200 and may optionally provide lighting configuration data to a controller of
the puck-shaped adaptable lighting unit 200. In some embodiments, of the puck-shaped
adaptable lighting unit 200 it may not be desirable or possible to drive all of the
LEDs at full power. Power may instead be distributed over a sub range of the LEDs
(
e.g., as illustrated in FIG. 2B) and/or all of the LEDs may be driven at a lower intensity.
The particular light output distribution may be generated in accordance with predefined
lighting configuration data received in response to integration of the puck-shaped
adaptable lighting unit with a particular lighting implementation.
[0046] FIG. 3A illustrates an oval-shaped adaptable lighting unit 300 generating a first
light output (generally represented by arrows emanating from the lighting unit 300)
that is generally directed in a radial direction three-hundred-sixty degrees around.
FIG. 3B illustrates the oval-shaped adaptable lighting unit 300 generating a second
light output (generally represented by arrows emanating from the lighting unit 300)
that is generally directed in a radial direction approximately two-hundred-forty degrees
around (with two approximately sixty degree gaps).
[0047] The oval-shaped adaptable lighting unit 300 includes an outer shell having a radial
light emitting surface 316. At least the perimeter of the outer shell is translucent
and encloses a plurality of LEDs. In some embodiments the LEDs may include LEDs generating
a collimated beam with a fine grained control. An external power connection 301 may
provide power to the LEDs of the oval-shaped adaptable lighting unit 300 and may optionally
provide lighting configuration data to a controller of the puck-shaped adaptable lighting
unit 300. In some embodiments of the oval-shaped adaptable lighting unit 300 it may
be desirable to directionally control the light output from the LEDs. For example,
as illustrated in FIG. 3B only certain of the LEDs may be illuminated to only provide
partial radially arranged light output.
[0048] In some embodiments, the directionality of the lighting may be controlled by a directionality
data communication optionally provided with received lighting configuration data (
e.g., provided over power connection 301 or in combination with received lighting configuration
data). For example, in some embodiments directionality of the lighting can be controlled
by two bytes. For instance, in some embodiments the first light output of FIG. 3A
may be generated in response to a directionality data communication of "11111111 11111111"
and the second light output of FIG. 3B may be generated in response to a directionality
data communication of "00011111 11110000." Other light outputs may be generated in
response to other directionality data communication. The particular implemented light
output may correspond to predefined lighting data receive in response to integration
of oval-shaped lighting unit 300 in a particular implementation.
[0049] FIGS. 4A and 4B illustrate a lighting fixture having an adaptable lighting unit 400
mounted atop a pole 401 and surrounded by a lamp shade 403 (and without uplighting
402 and downlighting 404). The adaptable lighting unit 400 is able to create segmented
lighting effects. For example, in FIG. 4A the lighting unit 400 is generating a first
light output with uplighting 402 and downlighting 404. Also, for example, in FIG.
4B the adaptable lighting unit 400 is generating a second light output with shade
lighting 406 directed toward the shade 403. Additional and/or alternative segmented
lighting effects may optionally be achievable from adaptable lighting unit 400.
[0050] In some embodiments the segmented output, the intensity, and/or other characteristic
of the light output of the lighting unit 400 may be adjusted based on received lighting
configuration data. For example, in some embodiments an RFID tag may be installed
on the shade 403 that may provide lighting implementation data to an RFID reader of
the lighting unit 400 that is indicative of the intended lighting implementation of
the lighting fixture (
e.g., for reading, for ambient lighting only, and/or for uplighting). The adaptable lighting
unit 400 may then obtain lighting configuration data (
e.g., from local memory) corresponding to the intended lighting implementation and adjust
light output characteristics of the adaptable lighting unit 400 accordingly. For instance,
if the intended lighting implementation is for ambient lighting and uplighting only,
the lighting configuration data may be utilized to adjust adaptable lighting unit
400 to be configured to cycle through providing shade lighting 406 only, uplighting
402 only, and a combination of shade lighting 406 and uplighting 402.
[0051] FIG. 5A illustrates a side section view of another modular adaptable lighting unit
500 having a multiple layer adaptable lighting unit module 540 with multiple light
emitting layers 540A-G. In FIG. 5A a diffuse lighting unit module 524 is received
within a recess 514 of the multiple layer adaptable lighting unit module 540 and powering,
communications, and optionally control is received from a side connection 501. A spotlighting
unit module 522 has been received within a recess 518 of end diffuse lighting unit
module 516. The diffuse lighting unit modules 516, 522, 524, and 540 have also been
coupled to one another. The power lines 501, 517, and 542 have also been electrically
coupled to one another and are electrically coupled to the spotlighting unit module
522 and the diffuse lighting unit module 524.
[0052] The light emitting layers 540A-G are stacked atop one another in a stair-stepped
arrangement. The light emitting layers 540A-G surround a concentric recess 549 in
the multiple layer adaptable lighting unit module 540. A plurality of LEDs 541A-G
are arranged in the recess 514 interior of the light emitting layers 540A-G and produce
light output directed toward respective light emitting layers 540A-G. In some embodiments
the LEDs 541A-G associated with each of the light emitting layers 540A-G may be individually
controlled to enable individual control of light output from each of the light emitting
layers 540A-G. In some embodiments a groups of one or more LEDs 541A-G directed toward
a single layer 540A-G may be individually controlled. For example, as illustrated
in FIG. 5A only one LED 541F may be illuminated to only illuminate a segment of light
emitting layer 540F and produce a collimated beam 503F.
[0053] Referring to FIGS. 5B and 5C, a top section view of the light emitting layer 540A
and a side section view of the light emitting layer 540A are illustrated. In some
embodiments one or more of the other light emitting layers 540B-F may have configurations
that are similar to the light emitting layer 540A. A plurality of LEDs 541A are circularly
arranged around the recess 514 interior of the light emitting layer 540A. Each of
the LEDs 541A is positioned so that light output therefrom is directed toward the
light emitting layer 540A and is coupled with a collimator 542A to ensure light output
therefrom is directed toward the light emitting layer 540A. Light from the LEDs 541A
enters into the light emitting layer 540A and exits as light output from the periphery
of the light emitting layer 540A. In some embodiments groups of one or more of the
LEDs 541A may be individually controllable (
e.g., may be individually turned on/off, may have brightness individually controlled, and/or
may have color individually controlled). An outcoupling optic 544A may optionally
be provided along all or a portion of the periphery of the light emitting layer 540A
to ensure exiting light is coupled out in a collimated beam with a desired angle and/or
direction. In some embodiments the light emitting layer 540A may include Poly methyl
methacrylate (PMMA).
[0054] In some embodiments one or more of the lighting unit modules 516, 522, 524, and 540
may have one or more adjustable light output characteristics such as one or more of
those described herein. Such light output characteristics may be adjusted based on
the particular lighting implementation as conveyed via received lighting configuration
data. For example, the light output characteristics of each light emitting layer 540A-G
may be individually adjusted to accommodate a particular installation location. For
instance, to achieve desired cut-off only certain of the light emitting layers 540A-G
may be illuminated and/or to achieve a certain distribution only certain of the LEDs
541A-G within an illuminated light emitting layers 540A-G may be illuminated.
[0055] FIG. 6 illustrates a schematic diagram of an embodiment of an adaptable LED-based
lighting system. The adaptable LED-based lighting system includes an adaptable LED-based
lighting unit 600 having a controller 650, a driver 655, and a plurality of adjustable
LEDs 641. In some embodiments the controller 650 and/or driver 655 may be provided
separate from the LED-based lighting unit 600. In some embodiments the controller
650 and the driver 655 may be integrated as a single component. In some embodiments
the adaptable LED-based lighting unit 600 and adaptable lighting units 100A, 100B,
200, 300, 400, and/or 500 may share one or more common aspects. In some embodiments
the adaptable LED-based lighting unit 600 may be replaced and/or supplemented with
one or more of adaptable lighting units 100A, 100B, 200, 300, 400, and/or 500.
[0056] Lighting configuration data 651 is supplied to the controller 650 to enable the controller
650 to adjust one or more adaptable light output characteristics of the LEDs 641 in
accordance with the lighting configuration data 651. The supplied lighting configuration
data 651 is specific to one or more aspects of the particular lighting implementation
within which the adaptable lighting unit 600 is implemented. For example, the adaptable
lighting unit 600 may be installable with a plurality of lighting fixture types and
may be operable with different light output characteristics for each of the different
lighting fixture types. The supplied lighting configuration data 651 may enable the
controller 650 to appropriately adjust light output produced by the LEDs 641 in accordance
with the lighting configuration data 651. For example, the controller may adjust characteristics
of the driver 655, sensor inputs, optics paired with the LEDs 641, and/or one or more
adjustable surfaces supporting the LEDS 641 to adjust the characteristics of light
output produced by the LEDs 641.
[0057] In some embodiments, the lighting configuration data 651 may be implemented in memory
associated with the controller 650. In some embodiments the lighting configuration
data 651 may be stored elsewhere (
e.g., lighting fixture, external database) and sent to the controller 650 using one or
more communication protocols and/or communication mediums.
[0058] In some embodiments, the controller 650 may receive lighting implementation data
606 representing a particular lighting implementation within which the LED-based lighting
unit 600 is implemented; may associate the lighting implementation data 606 with corresponding
lighting configuration data 651; may receive the corresponding lighting control data
651; and may control the LEDs 641 in accordance with the lighting configuration data
651.
[0059] In some embodiments, the lighting implementation data 606 may include identification
of one or more of an identifier representing a specific lighting fixture (e.g. Philips
Lirio Posada white LI 37362/31/LI), lighting fixture type (e.g. wall-mounted white
shade or arm creating ambient light) or a specific lighting effect (e.g. "effect nr
131"). In some embodiments the lighting implementation data 606 may be received via
an RFID tag reader integrated in the LED-based lighting unit 600. The RFID tag reader
may detect an RFID tag integrated in the lighting fixture or in a specific lighting
fixture part (such as an interchangeable lamp shade or diffusing plate). The LED-based
lighting unit 600 or other lighting part may also optionally be offered with "RFID
tag stickers" enabling end-users to "retrofit" their "old" luminaires. For example,
a plurality of RFID tag stickers may be provided in combination with the LED-based
lighting unit 600 with each being configured for a different lighting fixture type
within which the LED-based lighting unit 600 may be utilized. A user may select an
appropriate RFID tag sticker and install the RFID tag sticker on the lighting fixture
within which the LED-based lighting unit 600 is to be implemented.
[0060] In some embodiments, the lighting implementation data 606 may be received via a network.
For example, if the LED-based lighting unit 600 is IP connected (e.g., directly or
using a ZigBee - Wifi bridge), a user may utilize a mobile device (e.g., smartphone
or tablet computer) to send the lighting implementation data 606 to the LED-based
lighting unit 600. For example, this may done by selecting the lighting fixture from
a catalog in an application executing on the mobile device, typing in the serial number
of the lighting fixture (
e.g., shown on the package), or capturing a QR code with the mobile device (
e.g., on the package of the lighting fixture or back of the lighting fixture).
[0061] In some embodiments, the lighting implementation data 606 may be received via an
active communication element such as ZigBee or other RF communication that is activated
when the LED-based lighting unit 600 is implemented in the lighting fixture. For example,
the active communication element may be part of the lighting fixture within which
the LED-based lighting unit 600 is installed and may broadcast the lighting implementation
data 606.
[0062] In some embodiments, once lighting implementation data 606 has been detected, the
lighting implementation data 606 may be associated with appropriate lighting configuration
data 651 utilizing a look-up table which maps the lighting implementation data 606
to a set of associated lighting configuration data 651. In some embodiments the look
up table may be located within local memory coupled to the controller 650. In some
embodiments the controller 650 may be connected to a network and the network may be
utilized to identify lighting configuration data 651 that is associated with lighting
implementation data 606.
[0063] In some embodiments, a device may directly provide the lighting configuration data
651 to the LED-based lighting unit 600 and optionally not provide the lighting implementation
data 606. For example, the lighting fixture within which the LED-based lighting unit
600 is installed may provide the lighting configuration data 651 directly to the multi-effect
LED module. The lighting configuration data 651 may be stored locally at the lighting
fixture (
e.g., a controller of the lighting fixture), or in an electronic device embedded in the
lighting fixture. The lighting configuration data 651 may optionally include priority
data that indicates whether the lighting configuration data 651 represents "allowed"
settings for the lighting fixture, or represents "preferred" settings for the lighting
fixture. Allowed settings are settings that must be implemented to enable operation
of the LED-based lighting unit 600 within the lighting fixture. In other words, if
the LED-based lighting unit 600 is incapable of operating the allowed settings it
may be prevented from operating in the lighting fixture. Preferred settings for the
lighting fixture represent settings that are preferable to be implemented, but operation
of the LED-based lighting unit 600 within the lighting fixture is still enabled if
the LED-based lighting unit 600 is incapable of implementing the settings.
[0064] In some embodiments, a physical connection is used to set up a communications connection
between the LED-based lighting unit 600 and the lighting fixture to enable the lighting
fixture to directly provide the lighting configuration data 651. For example, wiring,
connectors, USB connection, and/or electronic communication bus (
e.g., a serial bus, power line communication, and/or USB connection) may be utilized to
communicate lighting configuration data 651 to the LED-based lighting unit 600.
[0065] In some embodiments, the lighting fixture can communicate a set of primary light
output characteristics (light distribution, color temperature, etc.) in the lighting
configuration data 651 that are compatible with the lighting fixture. Additionally,
the lighting fixture can communicate an alternative set of light output characteristics
in the lighting configuration data 651 if the LED-based lighting unit 600 is not capable
of fully reproducing the desired primary light output characteristics. The lighting
fixture may also provide in the lighting configuration data 651 a mode of operation
that defines which light output characteristics are controllable by one or more user
interface and/or parameters and ranges of the controllable light output characteristics
(
e.g., it can define how dimming should operate). In some embodiments a lighting fixture
may contain a plurality of LED-based lighting units and one or more of such LED-based
lighting units may provide lighting configuration data 651 to other of the LED-based
lighting units.
[0066] The light output characteristics that may be contained in the lighting configuration
data 651 may include one or more of a plurality of adjustable light output related
characteristics of a light source. For example, some light output characteristics
may relate to a single light output characteristics such as static light output characteristics
and/or dynamic light output characteristics. For instance, a simple fade-in / fade-out
may be defined which makes one or more of the LEDs 641 of the LED-based lighting unit
600 switch on and off in a gentle fading manner.
[0067] Also, for example, some light output characteristics may relate to a set of lighting
output characteristics such as a set of static light output characteristics and/or
dynamic light output characteristics. For instance, the lighting fixture and/or a
connected device (
e.g., a mobile device) may offer a user interaction means enabling a user to select a desired
lighting effect from a set of lighting effects set in accordance with the lighting
configuration data 651.
[0068] Also, for example, some light output characteristics may relate to one or more adaptive
or interactive lighting effects. For instance, a dynamic lighting effect may be implemented
in the LED-based lighting unit 600 that changes based on sensor input and/or user
input based on settings obtained via the lighting configuration data 651.
[0069] Also, for example, some light output characteristics may relate to a range of lighting
effects. For instance, instead of defining a set of separate effects, a range of effects
may be defined by particular parameter ranges allowing specific variations in light
output characteristics such as intensity, beam width, color temperature or light distribution
over defined segments of LED-based lighting unit 600. During operation, the LED-based
lighting unit 600 may control those parameters within the defined ranges based on,
intra alia: (1) user interface input (
e.g., using the luminaire UI, or using UI means on a connected device such as remote control
or smartphone) or (2) sensor input (
e.g., ambient light intensity, proximity of people, sensed mood in a room, the amount of
people present, etc.). Any utilized sensors may be available in the LED-based lighting
unit 600, in the lighting fixture, and/or in other connected devices in the proximity
of the LED-based lighting unit 600.
[0070] In some embodiments, the controller 650 may interface with the driver 655 to enable
each individual LED to be driven with the proper parameters in order to create the
desired light output characteristic. In some embodiments a specific lighting fixture
can have a set of predefined lighting configuration data associated with it and a
selected of the predefined lighting configuration data 651 will be supplied to the
LED-based lighting unit 600. In some embodiments the supplied lighting configuration
data 651 may be dependent on the type of LED-based lighting unit 600. In some embodiments
the supplied lighting configuration data 651 may additionally and/or alternatively
be dependent on one or more additional factors. For example, in some embodiments lighting
configuration data 651 is selected based on other inputs such as time/date input from
specific sensors. For instance, an outdoor lamp may provide different lighting configuration
data 651 based on a variety of parameters, such as time of day, ambient light level,
presence and/or proximity of a person, etc. An atmosphere lamp in the living room,
however, may offer a set of pre-defined light scenes to a user through a user interface.
This set of light scenes may also optionally be dependent on detected activities in
the room (
e.g., detection of kids or detection of party crowd) or time of year (e.g. specific Spring
or Christmas scenes). Lighting settings do not have to be static, but may also include
dynamic scenes which gradually change over time (e.g. a wake up experience) or adaptive
scenes which change upon sensor input (e.g. gradually increase of light intensity
upon detecting dawn or arrival of people).
[0071] In addition to or as an alternative to adaptable light output characteristics, it
is also possible to activate particular user interaction features for specific lighting
fixtures. For instance, for a lighting fixture which is quite open and usually within
reach of its users, the LED-based lighting unit may support touch control by touching
the module. Also, for instance, if a pendant ceiling lighting fixture is open at the
bottom side, specific gestures underneath the LED-based lighting unit may enable control
of the LED-based lighting unit.
[0072] FIG. 7 illustrates a flow chart of an embodiment of a method of adapting an LED-based
lighting unit to a particular lighting implementation. Other embodiments may perform
the steps in a different order, omit certain steps, and/or perform different and/or
additional steps than those illustrated in FIG. 7. In some embodiments a controller,
such as controller 650 and/or controllers described in combination with other embodiments
of adaptable lighting units described herein, may perform the steps of FIG. 7. At
step 700 lighting configuration data specific to a lighting implementation is received.
For example, the controller 650 may receive lighting configuration data from local
memory that correlates to received lighting implementation data. At step 705 one or
more lighting output characteristics is adjusted in accordance with the received lighting
configuration data. For example, the controller 650 may adjust the light output characteristics
of LEDs 641 to correspond according to the received lighting configuration data.
[0073] While several inventive embodiments have been described and illustrated herein, those
